DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

The hint offering to background a long Bash command is gone

You'll notice
Useful3 Signal3
Bash Tool

Bash no longer suggests backgrounding a long-running command; commands can still end up backgrounded when a turn is aborted.

What

Bash no longer shows the prompt telling you a long-running command can be moved to the background; that plumbing is deleted rather than relocated, going from 14 occurrences in 2.1.246 to none. In its place the tool result gained backgroundedByTurnAbort, documented as true when a plugin's turn abort moved the running command to the background.

Details
  • The tool now passes a caller identity into the shell runner.
  • The persisted-output path passes the session's storage version through to the directory-ensure call.
  • Unconditional; nothing gates it.
Evidence

@internal True if a plugin's turn abort moved the running command to the background

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
